Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v9.5 (Windows/Linux)

Hello, i have looked at a lot of the pages in this thread but can not find my issue. I have 5 GTX 1060 msi 3gb cards, trying to use claymore miner. It starts to mine fine then crashes with the following error.

GPU 1, GpuMiner cu_k00 failed 4, unspecified launch failure
GPU 1, GpuMiner kx failed 1
GPU 3, GpuMiner cu_k00 failed 4, unspecified launch failure

also, device manager shows 5 gpus, but claymore only finds 4. Any tips on this as well.

any help would be appreciated.

I have the same issue with him! My rig have 6 VGA Giga 3gb, but 1st VGA stoped Sad

Have anyone help us Sad

If you are having a single card first (others may fail afterward but usually starts with the same card), check your riser. specifically I would replace the cheap USB cable that comes with it along with the power adapter if you are using it. That's where most of my failures have been from. The other thing to check is to put a meter at the wall and see what your total draw is and make sure you are not maxing out your power supply.

i have a 850 power supply and each card is using 105-110 watt, so i should have plenty of power. Also, the issue happens with 4 cards installed not even 5. Currently , i have three of the cards on the board and only one using the riser and still get the same message. three cards on the board alone run no problem. I am trying to get 4 stable before i work on the 5th. I do not know why the error keeps coming up. I will try to replace the usb cord and the molex to sata. I also have another riser board on the way from a different and better company(according to the reviews). Any other suggestions are appreciated.

It is not caused by the risers as I had the same issue with NVIDIA 1070 cards plugged in directly. It is not the OC (also happens at stock clocks) but the dcri value pushed over 35-40 that causes it. Tested with version 9.3 and 9.5. It only seems you could push the secondary coin (Sia in my case) much further (and earn more with dual mining than with equihash) as the ethash hash rate doesn't change at all until 40-ish. But then when you push it further, the miner actually fails with the error mentioned above. Not sure whether it is a Claymore bug or driver or something else that causes it. I would really appreciate an input from @Claymore regarding the issue.

From what i understand from your reply, dual mining is causing the issue? So if i just mine ETH (nicehash technically) i should not see the issue? It also seems i can run 3 cards for the most part no issue. The second i stop reboot and plug in that 4th , mining freezes, or i get that error message. Obviously my goal is to get all 5 running, but i will settle for a stable 4 crads for now.
